To all whom it may concern Be it known that we, JOHN ROBERTSON MUNN andGEORGE MAGLAREN, subjects of the King of the United Kingdom of GreatBritain and Ireland, and resident of Glasgow, Scotland, have invented acertain new and useful Improvement in Collapsible Life-Boats and thelike, of which the following is a specification.

This invention relates to bulwarks for collapsible lifeboats or the likeand it consists in a construction comprising substan` tia-ily plane midportions adapted to fold inwardly in relation to the boat, and endportions accommodated in said mid portion or portions when the lifeboatis collapsed and slidable endwise relatively thereto when the lifeboatis to be launched, said end portions being of such formation and (or)material that they may be bent to conform to the contour of the boat,but will not be liable to be formed transversely.

A bulwark embodying the invention is illustrated in the accompanyingdrawing in which- Figure 1 is a fore and aft section showing the bulwarkextended. Fig. 2 a plan view and Fig. 3 a thwartship section.

Referring to the drawing, 1 denotes the mid portions of the bulwarkwhich are hinged at 2 to fold inwardly as shown in Fig. 3. The midportions 1 are formed with recesses and grooves to receive the endportions 4, such end portions being slidable in relation to the midportions so as to form extensions serving to bridge the gaps between themid portions and the stems 5 of the boat. The said end portions 4 areiieXi ble so that they may be bent to conform to the contour of theboat. The end portions i Specification of Letters Patent.

the same purpose. To insure that the bulwark shall be water-tight, theends of the said end portions 4 are adapted to enter re` cesses in thestems 5 which latter are capable of folding inwardly. The upper and thelower edges of the end portions 4 are guided in grooves, the upper edgesengaging recesses in movable gunwales 6 and the lower edges engagingrecesses in fixed guides 7.

It is to be understood that the invention in its broader aspects is notlimited to the precise construction shown nor to any construction bymeans of which the invention may be carried into effect, since manychanges may be made without departure from the essence of the inventionas defined by the appended claim.
